filter press for sand washing sludge treatment | lzzg

The filter press is a fully-automated system for sludge water treatment for sand washing plant, concrete manufacturing plant, industry wastewater. does not require operator assistance and in most cases, no additional chemicals are needed. The sludge is sent to every sealed filter chamber by the feeding pump with pressure, going into filter plates and filter cloths. The clean water will be filtered out from the filter plate water outlet by the filter cloth, but the solid is kept in the chambers to separate solid and liquid, finally, we will get the slurry cake to contain 25% water.

When the Filter press is operated, the sludge is discharged from the feed inlet into the filter cylinder and is moved to the discharge port by the push of the spiral shaft rotary vane. The pitch is gradually reduced, so the pressure of the sludge is also increased, and the pressure difference is started to be dehydrated, and the water is from the fixed ring and the activity. The annular piece is filtered out of the gap, and the filter press depends on the self-cleaning function between the fixed plate and the movable plate, and the clearance between the filter and the filter is prevented from being blocked. After fully dehydrated, the discharge is discharged from the discharge port under the action of the propeller shaft.

1. Providing efficient cleaning support to sludge accumulated in wastewater. 2. The machine works on the principle of pressure feeding that provides for optimum output support. 3. Supports a reduction in moisture content of sludge significantly. 4. Working as the solid-liquid separation device, the system can also be custom tuned as per the specific work process needs of customers. 5.Suitable for dewatering low and high concentrated sludge.

The plate and frame filter press is the first machine used in chemical dehydration. Although the plate and frame filter press generally has an intermittent operation, the large investment in infrastructure equipment, and low filtration capacity, it has large filtration driving force, the high solid content of filter cake, clear filtrate, high solid recovery rate, and conditioning medicine. The advantages of low consumption and so on are still widely used in some small sewage plants.

Rack section The frame part is the main body of the machine to support the filter mechanism and connect other components. It is mainly composed of a thrust plate, a pressing plate, a cylinder block and the main beam.

Pull plate part 1. The automatic pull plate part The automatic pull plate portion is composed of a hydraulic motor, a robot, a transmission mechanism, and a suspension device. 2. The manual pull plate part Manually pull the plate to discharge the material.

1. Corrosion-resistant rubber coated and reinforced thick steel plate material molding (SRRM) so that the filter plate can be long-lasting and non-deformable. Many manufacturers purchase the commercially available rubber-coated steel plate, which is not easy to deform.

Sand Washing comes in many forms and covers a range of feed and products produced, including construction aggregates such as concrete, asphalt, mason, mortar, and plaster sands; sports sands such as for golf courses, ball parks, and race courses; industrial sands, such as glass, filter, foundry, and frac; specialty sands and materials such as anti-skid, roofing granules; deligniting/organics removal; and soils washing for environmental projects.

First, consider the following questions: What do you have? What do you want to make? If the answer is a very specialized gradation and a difficult natural sand deposit, then consider a Recipe Plant. If the answer is a manufactured sand and you are making concrete sand all day every day, then an Ultra Sand Plant or Modular Wash Plant may be your answer.

Many other factors, such as available investment, local competition and expanding markets, will influence this decision. Through a process of elimination starting with the simplest configuration, McLanahans experienced personnel will guide you through to the best options.

Ultra Sand Plants, which utilize Dewatering Screens, Pumps and Cyclones, offer greater separation efficiency and provide a higher product yield that can be reused almost immediately due to the effectiveness of the Dewatering Screen. Ultra Sand Plants are commonly used to wash and dewater industrial and specialty sands, as well as asphalt, concrete and masonry sands.

Classifying Tank Based Sand Plants can create multiple products from a single feed as well as remove slimes and excess water. Feed material enters the Sand Classifying Tank first, and sand grains settle in sections according to size down the length of the tank. Valves at the bottom of each section release the grains into one of several flumes used to create a primary, secondary or tertiary product, depending on the application. The discharged products are then dewatered by Dewatering Screens and/or Fine Material Screw Washers. The addition of Cyclones and/or rising current water can be used to deslime the feed.

McLanahan Industrial Sand Plants are designed with a combination of McLanahan equipment to provide extremely sharp classification of various industrial sands. This equipment can include Attrition Cells, Dewatering Screens, Hydrocyclones, Hydrosizers, Filter Presses, Fine Material Screw Washers, Pumps, Separators and Thickeners.

Although Portable Plants, which can be wheel-mounted or skid-based to provide an ease of transport, are limited in capacity, they do not limit the process. Portable Sand Plants can be used for classifying, dewatering, sizing and removing oversize and organics from feeds to produce aggregates, construction and demolition materials, and specialty sands.

McLanahan Ultra Fines Recovery Plants can recover +400 mesh material for use in many industries. UFRs are especially well-suited in the aggregates industry for effluent streams containing <100 mesh fractions and for recovering valuable coal from effluent streams in the coal industry.
